Factsheet Energy Breakdown - Environment
PEOPLEPRACTICESSYSTEMS1 HVAC HESS heating , Ventilation & Air-Conditioning High Efficiency Systems Strategy September 2013 heating Ventilation and Air Conditioning (HVAC) is generally responsible for a significant proportion of total building Energy consumption. A typical system accounts for approximately 40% of total building consumption and 70% of base building ( landlord) consumption. The pie graph in Figure 1 shows the typical Energy consumption Breakdown of an office building, being 39% HVAC, 25% lighting, 22% equipment, 4% lifts, 1% domestic hot water and 9% 1: Typical Energy consumption Breakdown in an office building1 There are a number of key end uses in HVAC systems.
the production of hot water for heating, but also the use of electric heaters for zonal reheat, accounts for 17% of consumption ` P umps for the circulation of hot water, chilled water and condenser water, account for 16% of consumption ` C ooling towers for heat rejection, being primarily the cooling tower fan energy, account for 6% of ...
